#11. I was under the impression that not Payne used up the placeholder since the condition was not O and not P sharing the placeholder with not M. Does that mean that in these conditional statement which are very common that I get 2 placeholders 1 for not O and not M and the other for Not P and not M. It's critical because with just one it made the question very time consuming.
Yes; you've got it. See this video for a full explanation.
when you wrote the contrapositive for the rules why did you write for example T OR P instead of T+ P. For Q11. When I was putting in the "out", if P and S is out, I thought well that means T must also be out but you didn't write it that way. Why is that? Is it because the contrapositive of the rule that says MUST would be could/or? must (contra)= could be/or
See this video for an explanation (you should watch the Theory videos! They're full of helpful info!).
If we connect the chain we also get M arrow /S. Why do we not make a placeholder for that one as well? Is it because in both instances we can just have M out and both S and O in?
